Title: A direct-voltage measuring system
IPC: G01R17/06
Filed: 1968-07-17
Abstract: 1,239,828. Voltage measurement. CAMILLE BAUER MEBINSTRUMENTE A. G. July 17, 1968 [July 18, 1967], No. 34062/68, Heading G1U. A direct voltage U E  to be measured is applied to voltage-dependent capacitance diodes 11, 12 in the feedback path of an unstable A. C. amplifier 3, and the resultant change in the magnitude of the oscillations of the amplifier due to the change in diode capacitances is compensated by adjustment of mechanically variable capacitors 13, 14 in the amplifier feedback path, this adjustment providing a measure of U E  . Preferably the two capacitance diodes 11, 12 and associated differential capacitor 13, 14, constitute two arms of a bridge circuit, the other two arms being constituted by the centre-tapped secondary winding of the amplifier output transformer 4. An auxiliary D.C. supply 5, providing an initial bias for the diodes, is adjusted by resistor 9 to cause the amplifier to oscillate at a predetermined level when U E  = 0. Application of a voltage U E  of either polarity causes a change in the level of the oscillations which is detected by an amplitude discriminator 10 to cause A.C. servomotor 6 to drive the rotatable plate 2 of the differential capacitor so as to rebalance the system. A pen recorder 7 is coupled to the motor shaft. A D.C. servomotor may alternatively'be used, in which case the output of amplifier 3 is rectified and supplied to the motor in opposition to a direct voltage so that the motor responds only to deviations of the oscillations from their normal level.

Title: Improvements relating to electric toasters
IPC: A47J37/08
Filed: 1947-12-29
Abstract: 637,610. Grilling and toasting. HOOVER, Ltd., Dec. 29, 1947, Nos. 34417 and 34418. Convention dates, Dec. 31, 1946. [Class 28(i)] [Also in Group XXXVII] A temperature responsive timing mechanism for an automatic toaster comprises a bi-metallic strip 35, heated by a resistance heater partially enclosed by a reflector 40. A spring 37 provides compression of the bi-metallic strip which is energized so that it will assume an upwardly bowed position when cool, and downwardly bowed position when hot with a snap action past a central unstable position. When the toaster is operated by depressing an operating lever 20 to lower the toast carriers of usual type into a toasting position a cam 74 co-operating with a cam face 75 closes contacts 70, 71, energizing the heaters including the heater beneath the reflector 40. When the bimetallic strip 35 has absorbed sufficient heat it snaps into the downward position and operates a latch 28 retaining the toast carrier in the lowered position, to enable the carrier to be raised by a spring into the loading position and also to break the contacts 70, 71 thus de-energizing the heaters. In its upward movement the toast carrier, carries a camming link 54 against a cam surface 56 of a cooling block 51 raising it from a lowered position to a position in contact with the bi-metallic strip when it is retained by a latch 58. When the bi-metallic strip is sufficiently cooled it snaps back to the upward position and carries with it a link 57 which pivots about a pin 59 and releases the latch 58 allowing the cooling block to drop away from the bi-metallic strip into the lowered position. If a second toasting operation is initiated before this cycle is completed the carrier is latched down as before, but the heaters are not energized since contact 70 is displaced away from contact 71 until the link 57 is carried upwards by the bi-metallic strip returning to its upward, cool position. In this manner the start of each toasting cycle is delayed until the bi-metallic timing element has been cooled and a uniform result is obtained even if the toaster becomes progressively more heated. A shield 41 pivoted within the reflector 40 and controlled by a knob 46 via link 43 may be adjusted to vary the amount of heat radiated to the bimetallic strip 35 in order to vary the length of the toasting period and hence the colour of the toast.

Title: An improved roll press for squeezing liquid from solid or pulpy material
IPC: B30B9/20
Filed: 1953-12-11
Abstract: 751,757. Roll presses for dejuicing fruits. WILLMES, J. Dec. 11, 1953 [Dec. 13, 1952 ; Oct. 26, 1953 ; Oct. 26, 1953], No. 34585/53. Class 14(2). A roll press for squeezing solid or pulpy products e.g. fruits, between rolls comprises a number of peripheral rolls 17 &c. which bear against at least one central roll 3 which is hollow, filled with a fluid pressure medium and has a wall of elastic material. The peripheral rolls may also be hollow, elastic walled and contain pressure fluid. In operation, fruit is fed by a hopper 44 past rollers 45 which remove some juice to an outer endless conveyer 37 which is guided by rollers 38. An inner conveyer 36 forms an opening 58 with the outer conveyer and both pass into a pressing chamber 34 between the central roll and peripheral rollers. Both or only one of the conveyers may be of yieldable and liquid impermeable material. Expressed juice collects in a trough 65 and is discharged through a duct 65a. Solid residue is removed by means 39, 40 and 41 and passes to surfaces 62 and screen 63. The peripheral rolls, either motor driven or hand operated, rotate, by friction, the central roll and conveyer bands. The pressure inside the rolls may be atmospheric if the elastic walls are sufficiently thick, and the pressure may be varied by means of a diaphragm pump. The surfaces of the rolls may have depressions, and there may be means for cooling and/or heating at least one of the rolls. Modified feeding means to the press are described which partially dejuice the fruit. In modifications, a plurality of central rolls are associated with at least one common conveyer with a peripheral roll common to two central rolls. One of the peripheral rolls' may be hollow and have a porous outer wall, and it may surround the central and other peripheral rolls, and in these modifications one conveyer or none is' used, the pressing chamber being formed between the central roll and the porous peripheral roll, the expressed juice passing through the latter to collecting troughs. See e.g. Figs. 16, 17 and 18 (not shown).

Title: Sulfur and peroxide curable polyacrylates
IPC: C08F220/12
Filed: 1964-08-28
Abstract: Acrylic rubbers are prepared by polymerizing one or more acrylate or methacrylate esters of alkanols having up to 8 carbon atoms together with a minor proportion of dicyclopentadiene in the presence of a free radical polymerization initiator. The monomers may also include up to 30% by weight of acrylonitrile. Polymerization is preferably effected in an aqueous medium in the presence of a suspending agent such as sodium polyacrylate.  The initiator, e.g. azobisisobutyronitrile or benzoyl peroxide, is desirably added stepwise during polymerization, dissolved in a solvent such as benzene, methanol or xylene. The rubbers can be cured by heating in the presence of sulphur and/or a peroxide, e.g. dicumyl peroxide, benzoyl peroxide, lauroyl peroxide, t-butyl perbenzoate or 2,5-bis (t-butyl-peroxy) - 2,5 - dimethylhexane. Conventional rubber stock adjuvants may be included in the curing composition, e.g. reinforcing agents, fillers, plasticizers, antioxidants, age resistors, resins, dyes, pigments and fungicides; adjuvants exemplified are carbon black, stearic acid, zinc oxide and methyl zimate (a zinc derivative of a thiocarbamic compound).

Title: Improvements in and relating to fluid pressure braking apparatus
IPC: B61H13/32
Filed: 1920-12-17
Abstract: 176,900. Cloud, J. W., and Westinghouse Brake & Saxby Signal Co., Ltd. Dec. 17, 1920. Fluid-pressure; forcetransmitting mechanism. -In an application of the brakes air is first admitted to an auxiliary brake cylinder which causes the tie-rod connecting the brake levers to be moved transversely to bring the brake-blocks up to the wheels, the effective pressure being then applied by the main cylinder, which is connected to the brake lever in the usual manner. The brake-levers 5, 6 are connected respectively to the main piston-rod 7 and to the fixed bracket 9. The tie-rod 10, 11 is connected by an arm 15 to the piston-rod 16 of the auxiliary cylinder 13 and has rollers 13, 14 for slidable engagement with the levers 5, 6. The spring 19 is interposed between the auxiliary piston 17 and the base 20 of the cylinder and a second spring 21 between the base 20 and a flange 22 on a sleeve 36 within which the piston-rod 16 slides and which also slides in the cylinder 18. The cylinders 1, 18 are connected to the triple valve 3 by pipes 34, 31 respectively and normally are connected to atmosphere thereby. Upon a reduction of train-pipe pressure to effect an application of the brakes, the valve 3 first uncovers a port 30 by which air is supplied from the auxiliary reservoir 2 to the cylinder 18, whereby the tierod 10, 11 is moved transversely to actuate the levers 5, 6 and bring the brake-blocks into contact with the wheels. The movement of the piston 17 is opposed first by the spring 19 and subsequently by both springs 19, 21 so that the movement of the tie-rod takes place in two stages. When the triple valve reaches its application position, air is supplied in the usual way to the main cylinder 1 to develop the full braking pressure. As the extent of the downward movement of the tie-rod 10, 11 depends upon the clearance between the blocks and the wheels and this clearance depends, in some cases, upon the loading of the vehicle, the mechanical advantage of the transmission mechanism depends on the load. Thus notches 37, 38 may be formed in the levers 5, 6, the rollers 13, 14 being received in the notches 37 or 38, according as the vehicle is empty or loaded. A regulating-cock 35 adapted to be set in one or other of two positions to regulate the rate of flow of compressed air to the cylinder 1 may be provided. The triple valve may have a chamber 29 into which the train-pipe is seated in an application of the brakes or the train-pipe may be vented to the cylinder 18. Compensating for wear.-The tie-rod is in two parts 10, 11, the screwed ends of which are connected by a screwed bushing 39 having a ratchetwheel 41 engaged by a pawl 43 on a rocking-arm 44 connected by a link 46 to the base 20 of the cylinder 18. Thus, if the downward movement of the piston 17 and rod 10, 11 exceeds a predetermined amount, the pawl 43 slips a tooth and the bushing 39 is rotated to shorten the rod, during the return movement.
